Everything you need to know about aquarium betta fish

Whether you are looking for a brand-new or second-hand aquarium betta fish, eBay offers one of the largest selections available online. With 96 active listings at the time of this page's last update, you have plenty of choice across different conditions, sellers and price points. The cheapest option currently starts at £1.59, while premium listings can reach £312.7 — giving you a wide budget spread to work with. The average price of £21.92 can serve as a useful benchmark: listings below this tend to be used or auction-style, while those above often include extra accessories, warranties, or are sold by professional sellers with high feedback scores. Always check the seller's feedback rating and return policy before committing to a purchase. If you need the item quickly, filter by "Buy It Now" to avoid the uncertainty of auctions. For used items, look closely at the condition description and photos — terms like "good", "very good" and "like new" can mean very different things depending on the seller.
